Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor with rapid braking capability. Background Technology

[0002] Electric motors are essential components of modern industry and society. Their core function is to convert electrical energy into mechanical energy through electromagnetic induction. They are widely used in energy production, industrial drives, transportation, and intelligent control.

[0003] In some situations, mechanical equipment needs to stop immediately after a power outage. This requires the braking system of the mechanical equipment to have the characteristics of fast response speed and high braking reliability, such as mechanical equipment that requires precise positioning and control.

[0004] In existing mechanical equipment, the drive system and braking system are often separate, resulting in slow response speed and complex system structure. Therefore, it is necessary to develop a motor with fast braking capability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a motor with rapid braking capability. This motor integrates the braking system and drive system, achieving rapid braking, and features a simple structure, fast response speed, and high braking reliability to meet the rapid braking requirements of specific applications.

[0006] The technical solution of this application is as follows:

[0007] A motor with rapid braking capability includes a motor body and a rapid braking device. The rapid braking device is sleeved on the front output shaft of the motor body and connected to the front cover of the motor body. The rapid braking device includes a left braking assembly, a right braking assembly, and a mounting bracket. The left braking assembly includes a left brake box, a left compression spring, and a left friction plate arranged in sequence. A metal block A is provided on the side of the left friction plate near the left brake box. The right braking assembly includes a right brake box, a right compression spring, and a right friction plate arranged in sequence. A metal block B is provided on the side of the right friction plate near the right brake box. A limiting post is provided between the left and right brake boxes, and the limiting post passes through the left and right friction plates. Electromagnets are provided inside both the left and right brake boxes to attract metal blocks A and B.

[0008] Compared with the prior art, the motor with rapid braking capability of this application has a rapid braking device sleeved on the output shaft. When energized, the electromagnet attracts iron blocks A and B, respectively driving the left and right friction plates away from the output shaft, allowing the output shaft to rotate normally. When de-energized, the electromagnet releases the attraction of iron blocks A and B, and the left and right friction plates approach and press against the output shaft under the action of the left and right compression springs, respectively, achieving rapid braking. It has the characteristics of simple structure, fast response speed, and high braking reliability. Moreover, the rapid braking device is sleeved on the front output shaft of the motor body, which is convenient for installation and maintenance.

[0009] As an optimization, in the aforementioned motor with rapid braking capability, the left brake box is provided with a placement slot A, the left compression spring is placed in placement slot A, and the iron block A is placed inside the left compression spring and coaxial with it; the right brake box is provided with a placement slot B, the right compression spring is placed in placement slot B, and the iron block B is placed inside the right compression spring and coaxial with it. This structural design makes the rapid braking device more compact, and the coaxial arrangement of iron block A with the left compression spring and iron block B with the right compression spring improves the stability of the rapid braking device during operation.

[0010] As an optimization, in the aforementioned motor with rapid braking capability, the right brake box is equipped with an A-shaft bracket, which houses an A-shaft, and a handle is hinged to the A-shaft. The left friction plate is equipped with a B-shaft bracket, which houses a B-shaft, and an A-link is hinged to the B-shaft. The other end of the A-link is hinged to the upper part of the handle. The right friction plate is equipped with a C-shaft bracket, which houses a C-shaft, and a B-link is hinged to the C-shaft. The other end of the B-link is hinged to the lower part of the handle. With this structure, when the handle is pulled outward, the A-link pulls the left friction plate to press against the output shaft, while the B-link pushes the right friction plate to press against the output shaft, further enhancing the braking effect. Furthermore, in the event of an electromagnet malfunction, pulling the handle inward causes the A-link to push the left friction plate away from the output shaft, while the B-link pulls the right friction plate away from the output shaft, thus not affecting the rotation of the output shaft and allowing the motor to operate temporarily, reducing the impact on production progress.

[0011] Furthermore, in the aforementioned motor with rapid braking capability, the mounting bracket is equipped with bolts, and the handle is equipped with limiting holes. The bolts can fix the handle through the limiting holes. With this structure, in the event of an electromagnet malfunction, the handle can be pried inward and fixed with bolts, allowing the motor to operate temporarily without requiring the operator to continuously pry the handle, thus freeing up labor. Moreover, during installation, this structure allows the rapid braking device to be installed on the motor body without energizing the electromagnet.

[0012] Furthermore, in the aforementioned motor with rapid braking capability, the bolts are made of plastic. Using plastic bolts allows for quick braking by simply pulling the handle to break the bolts when manual emergency braking is required, saving time spent unscrewing them.

[0013] As an optimization, in the aforementioned motor with rapid braking capability, the mounting bracket includes a front connecting plate and a rear connecting plate. The rear connecting plate is connected to the front end cover of the motor body, and the front connecting plate is used to connect external mechanical equipment. This structure facilitates installation and connection to external mechanical equipment. Attached Figure Description

[0020] The present application will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present application. In the following embodiments, content not described in detail or shown in detail in the accompanying drawings is common knowledge in the art.

[0021] Example (see) Figures 1-5 ):

[0022] A motor with rapid braking capability includes a motor body 1 and a rapid braking device. The rapid braking device is sleeved on the front output shaft 11 of the motor body 1 and connected to the front cover 12 of the motor body 1. The rapid braking device includes a left braking assembly 2, a right braking assembly 3, and a mounting bracket 4. The left braking assembly 2 includes a left brake box 21, a left compression spring 22, and a left friction plate 23 arranged in sequence. An iron block A 24 is provided on the side of the left friction plate 23 near the left brake box 21.

An iron block B 34 is provided on the side of the right friction plate 33 near the right brake box 31. A limiting post 5 is provided between the left brake box 21 and the right brake box 31, and the limiting post 5 passes through the left friction plate 23 and the right friction plate 33. Electromagnets are provided inside the left brake box 21 and the right brake box 31 to attract iron blocks A 24 and B 34.

[0023] In this embodiment, the left brake housing 21 is provided with an A placement slot 211, the left compression spring 22 is disposed in the A placement slot 211, and the A iron block 24 is disposed inside the left compression spring 22 and coaxial with the left compression spring 22; the right brake housing 31 is provided with a B placement slot 311, the right compression spring 32 is disposed in the B placement slot 311, and the B iron block 34 is disposed inside the right compression spring 32 and coaxial with the right compression spring 32. This structural design makes the rapid braking device more compact, and the coaxial arrangement of the A iron block 24 with the left compression spring 22 and the B iron block 34 with the right compression spring 32 improves the stability of the rapid braking device during operation.

[0024] In this embodiment, in the aforementioned motor with rapid braking capability, the right brake box 31 is provided with an A-shaft bracket 312, the A-shaft bracket 312 is provided with an A-shaft 35, and a handle 6 is hinged to the A-shaft 35; the left friction plate 23 is provided with a B-shaft bracket 231, the B-shaft bracket 231 is provided with a B-shaft 25, the B-shaft 25 is hinged to an A-link 7, and the other end of the A-link 7 is hinged to the upper part of the handle 6; the right friction plate 33 is provided with a C-shaft bracket 331, the C-shaft bracket 331 is provided with a C-shaft 36, the C-shaft 36 is hinged to a B-link 8, and the other end of the B-link 8 is hinged to the lower part of the handle 6. With this structure, when the handle 6 is turned outward, the A link 7 pulls the left friction plate 23 to press the output shaft 11, while the B link 8 pushes the right friction plate 33 to press the output shaft 11, further enhancing the braking effect. In the event of an electromagnet malfunction, when the handle 6 is turned inward, the A link 7 pushes the left friction plate 23 away from the output shaft 11, while the B link 8 pulls the right friction plate 33 away from the output shaft 11, thus not affecting the rotation of the output shaft 11, allowing the motor to work temporarily and reducing the impact on production progress.

[0025] In this embodiment, in the aforementioned motor with rapid braking capability, the mounting bracket 4 is provided with bolts 9, and the handle 6 is provided with limiting holes 61. The bolts 9 can fix the handle 6 through the limiting holes 61.

Furthermore, during installation, this structure allows the rapid braking device to be installed on the motor body 1 without the electromagnet being energized.

[0026] In this embodiment, the bolt 9 in the aforementioned motor with rapid braking capability is made of plastic. Using a plastic bolt allows for quick braking by simply pulling the handle 6 to break the bolt 9, saving time spent unscrewing it.

[0027] In this embodiment, in the aforementioned motor with rapid braking capability, the mounting bracket 4 includes a front connecting plate 41 and a rear connecting plate 42. The rear connecting plate 42 is connected to the front end cover 12 of the motor body 1, and the front connecting plate 41 is used to connect external mechanical equipment. This structure facilitates installation and connection to external mechanical equipment.

[0028] When the motor with rapid braking capability in this embodiment is powered on, the electromagnet attracts iron block A 24 and iron block B 34, respectively driving the left friction plate 23 and right friction plate 33 away from the output shaft 11, allowing the output shaft 11 to rotate normally. When the power is off, the electromagnet releases its attraction to iron block A 24 and iron block B 34, and the left friction plate 23 and right friction plate 33 approach and press against the output shaft 11 under the action of the left compression spring 22 and right compression spring 32, respectively, achieving rapid braking. At this time, the handle 6 can be moved outward, and the connecting rod A 7 pulls the left friction plate 23 to press against the output shaft 11, while the connecting rod B 8 pushes the right friction plate 33 to press against the output shaft 11, further enhancing the braking effect.
